Pressure Service Carbon Steel Pipes refer to tubular equipment that use a certain pressure to transport gas or liquid. The maximum working pressure is greater than 0.1MPa. The medium is gas, liquid, steam, or combustible, explosive , toxic, corrosive with a maximum working temperature higher than the standard boiling point.A pipe that diameter greater than 50mm. Except for the pipes that transport non-toxic, non-flammable, non-corrosive gases and whose nominal diameter is less than 150mm and the highest working pressure is less than 1.6MPa.
Standard: GB,ASTM,EN,DID,JIS and so on
Package: In bundles, wooden box, Woven bag
Low pressure 0≤P≤1.6MPa
Medium pressure 1.6<P≤10MPa
High pressure 10<P≤100MPa
Ultra-high pressure P>100MPa
The inspection of Pressure Service Carbon Steel Pipes include: appearance, thickness measurement, non-destructive testing, hardness measurement, metallography, pressure test, etc. The ability of magnetic particle inspection is not only related to the intensity of the applied magnetic field, but also related to the direction of the defect, the aspect ratio of the defect, the shape of the defect, the shape, size and surface condition of the workpiece, and the location where the defect may occur. Therefore, there are various magnetization methods.
The same data, as well as additional information per customer’s request, is indicated on the bundle’s tags.
